Description

[0001] technical field

[0002] The invention relates to a spray control device, in particular to an automatic spray control device for a coal conveying belt in a mine, which is used to prevent dust from flying and needs to be sprayed when the belt conveys granular materials (such as coal, stone, sand, etc.). It belongs to the technical field of mine equipment. Background technique

[0003] From the physical properties of dust and the basic laws of its movement, as long as there is relative movement between dust and air, it may cause dust to fly. Dust not only affects normal production and the health of workers, but also causes environmental pollution. In severe cases, it may cause dust explosion, endangering life and production safety.

[0004] For material transportation that can be sprayed with water, the simple and effective way to prevent dust flying is to spray. How to carry out timely, appropriate and effective spraying is the most concerned technical issue in the p...
